I tried moving the blend valve adjustment and it did indeed improve the water temp but later in the day it was back to cold/luke warm again. Is that the usual outcome when the valves scaled up?
I just ran the hot water and the pipe between the heat/ex and blend valve became to hot to touch but the top blend valve pipework is only slightly warm. The strange thing is sometimes the water will run hot?
T hankyou both I will have another look tonight, it was serviced about a month ago by bthe guy that installed it 8 yrs ago but he said he could not find the fault? Judging by the time taken to service I dont think that he could of removed the blend valve.
Hi, sorry if this topic as been covered a million times before but I haven't found any definite answer on searches?
The water remains luke warm or cold most of the time, the hot water tap as to be run for about 5 minutes before anything like warm water comes through. The burner does not cut in...
